Description

Folded cardboard box with cart.

The present invention relates to a box of folded cardboard that incorporates a cart with wheels and a handle telescopic

Its field of application is that of the containers low price to transport relatively heavy products, and It has been specially designed to be used in gifts of Christmas company.

In this document the term "cardboard" represents any laminated, plasticized or no.

Background of the invention

Folded cardboard boxes are known to be used to transport batches of food products who usually give, for Christmas, businesses to their employees. These products are packed in boxes, sometimes quite heavy, that employees must take home with difficulty. For other part, the use of carts with wheels and a telescopic handle It is also known in its association to backpacks or bags of the purchase.

Thus, document ES 1 064 330 U describes the combination of a cart and a folded cardboard box Usually used for Christmas gifts. The union is made by rivets, as in the backpacks or bags of the purchase just mentioned. Unfortunately, cardboard is not a material that easily adapts to being joined by rivets as a result of its extreme weakness, so the document ES 1 064 330 U proposes a solution on which the riveting is supported in a reinforcement strips and the cart structure is formed by a rigid tray of high surface on which the guides for the telescopic handle are arranged. One such solution is face, because it requires a lot of tools. Additionally, the operation of Riveting of the set must be carried out by qualified personnel With the relevant tools.

Consequently, it is an objective of the present invention to have a folded cardboard box with cart that allow assembly, without tools, at the place and time of the incorporation of products to it.

It is another objective of the present invention the have a folded cardboard box with cart the most economical possible, that does not require specialized labor for its assembly, Do not require numerous manufacturing tools.

Description of the invention

The present invention incorporates a box of Conventional cardboard, with its lid. How it will be well known by the person skilled in the art, this type of box is configured starting from a sheet of cardboard stamped with cuts, holes and folding lines. The usual thing is that it is shaped to the box by two opposite folds, with flaps that are imprisoned by double folds provided on the other two sides. For his known carts usually have a structure of armed on which the wheels and the handle are arranged telescopic

Well, based on the fact that the problem posed resides in the union of the cart to the box of cardboard due to the weakness of the material, a solution in which the cart is trapped during the box folding operation, without the use of means of specific union.

To achieve the above, the cart will set up at least one working longitudinal tube of support, on which a top platform and a lower platform, the latter provided with wheels. Inside of the longitudinal tube plays an inner tube attached to the handle of transport. Both the upper platform and the platform infer, laminar in appearance and perpendicular to the longitudinal tube of support are designed to be imprisoned, along with the side flaps, for double folds during configuration of the box, which is provided with the appropriate holes for the  pass through both the wheels and the telescopic handle.

Additionally, in order that the whole Presents the necessary stability when resting vertically on the wheels, endowed with support legs, well to the platform Bottom of the cart, well to the lid of the cardboard box.

A special cut can also be provided in the stamping of the cardboard sheet that allows, after the appropriate folded, that the telescopic handle, in its retracted position, does not protrudes from the projection of the perimeter of the box, facilitating its stacking and palletizing.

The advantage of the folded cardboard box with cart object of the invention is that the assembly can be maintained disassembled (with unfolded cardboard) until the same moment of incorporate the products, which can be done by staff Not specialized Box and cart sympathize only with the product batch preparation.

Detailed description of a preferred embodiment

In figure 1 the lines of continuous line cutting and line folding lines discontinuous. The expert in the field, in view of this figure and of the rest of the accompanying details, you will easily understand the process of folding the box. This type of box (1) is configured acting primarily on the simple folds (2), whose flaps (3) subsequently they will be imprisoned by double folding (4) from the other two sides of the box (1). The accommodation of a plurality of tabs (5) in their corresponding grooves (6) block the folds made and prevent the box from disassembling accidentally. The specificity of the box of the invention lies in the wheel holes (7) and in the handle hole (8), which allow the respective elements of the cart to pass through of the box (1).

As for the cover (9) shown in shape laminate on the right side of figure 1, presents a distribution of cutting and folding lines similar to that of the box (1), with the only difference with respect to the configuration of a conventional cover of the presence of two crenellated cuts that will give place to light legs (10), support. Note that, not being the base of the square box, if not rectangular, the development Laminar cover (9) is rotated 90 ° to that of the box (1). The goal is to maximize the surface of the iron cardboard during die cutting, end that will be known by the skilled.

As for the cart, its structure is shown in figures 2 and 3 for variants with one or two tubes supports (11). To these, a superior platform (12) and a lower platform (13), is last provided with wheels (14). In each support tube (11) plays an inner tube (15) attached to a handle (16).

The assembly of the set, to attach the cart to the box (1) is shown in figures 6 and 7, and consists of imprison the upper platform (12) and the lower platform (13) between the double folds (4), while doing the same with the flaps (3). Figure 6 corresponds to the execution with two support tubes (11), while Figure 7 corresponds to the variant with only one.

As regards the execution of the handle, several cases can be combined, depending on whether the cart uses one or two support tubes (11) and depending on whether or not a housing is provided for the handle in retracted position, which facilitates stacking and palletizing the set. Thus, figures 8 and 10 show the preferred embodiment, which uses a single support tube (11) and a handle housing. In this case, the hole of the handle (8) is the one shown in figure 1 and is accompanied by two cuts parallel and three perpendicular folding lines, to give rise to to a structure that can be clearly seen in Figure 5. Note that, in this embodiment, the handle (16) does not protrude from the perimeter of the box (1). The handle hole (8) allows to pass this through it once turned 90 ° with respect to the drawing plane.

Figure 9 shows another variant in the that the handle (16) is attached to two inner tubes (15) and has not been planned accommodation for it, so it remains in a elevated position on the box (1) making stacking difficult. Do not it has been considered necessary to show, in this case, the plane of punching of the cardboard plate, as it is evident in the Figure 9 itself consisting of a flap-shaped cut.

Also as for the support legs they have provided two alternative variants. The preferred consists of a pair of light legs (10) made in the cover (9), whose die cut is shown in figure 1 and its final appearance can be seen in figures 5, 10 and 11. Alternatively, the lower platform (13) with a set of rigid legs (17) attached by a crossbar provided with extensions that fit into respective hollow protuberances (18), as shown in the Figure 12. Obviously, these rigid legs (17) can only engage the hollow protuberances (18) when they have passed  through the box (1).

They will be evident to an expert in the field a series of variations and alternatives that allow adapting the design to customer preferences and the possibilities of production. Thus, the cart will preferably be made in plastic material, except the support tube (11) that may require a metal construction depending on the weight to be transported. Not have represented the necessary means of joining the different parties of the cart, nor the means to limit the telescopic travel of the handle (16), which will be well known by the expert in the matter, and that can be done in multiple ways.
